We need the way to define specific visualizers of data specific for components and job classes. For instance, we need to visualize validation results that will come as data of Core for job class Validation on commits in Linux kernel Git repositories (#6593). Besides other components can provide some specific data for visualization.

Note that sometimes component data visualization will be specific for job classes, sometimes it should be visualized in the same manner for all job classes.

In future this visualization can include some interaction, e.g. to create a new job on the basis of this data and a job for what this data was obtained.
